Until Dawn's butterfly effect is a pretty interesting concept. Though choices in games has been around for a while now, Until Dawn may do it best. Though it isn't the greatest game around, it has elements that could make great games even better. Imagine future AAA titles implementing a ton of choices like Until Dawn does. There has been other games that adapts to the choices one make, but not at the level Until Dawn has done, and it could fair well for more studios to try to work such an option into their bigger titles.
